I've been using them for years and have given them a lot of abuse while camping, working in the garage and around the yard. No matter how I smash them, drag them across gravel or a driveway, they hold up. I change every two years or so but this is amazing as the velcro and clip just don't hold up. I use my phone all day and open the case probably 100 times a day to really stand up to abuse.
